You can! This is very common, especially for our students in school or university. Just let your teacher know what book you're using; they may also ask you for the curriculum provided by your teacher. Not in a class, but purchased a book already? We can use that too.

You may wonder, how could your teacher help if they don't have the book you have? Remember that your teacher is an expert language educator. If you say "next in our book we're working on regular tense ER verbs" your teacher will know exactly what you're working on. They don't need to necessarily have a physical copy of your book 🙂
